I feel Sis, that you are being a bit unfair on the Sis here for being non-Muslim. SubhanAllah, the doors to repentance do not close until the day we die. You & I don’t know what awaits her in the future, and what potential she has. She may have more potential than you or I, and could become a better Muslim than us. Ofcourse she can make Tauba. Allah Knows Best.

Why would she revert? If I were she, and I was duped by a muslim once, – and then when I approached some for help… I were shrugged off because they assumed I had sinned, and judged me, and told me as a non-muslim my chances for Tauba were slim… why on earth would I think Islam had anything to offer? Sis, the most beautiful thing about Islam, and the Sunnah of our Prophet was the humanity & Rahmah involved in it…   we should be inclusive in Islam, not exclusive.

Also, how can we tell if she ‘wants to’? Only Allah & she alone know that. I don’t think non-Muslims start out by ‘wanting to’ to accept Islam. Nobody plans or intends on leaving the religion of their forefathers. It only happens if they come across the benefits or truth that the other ideology offers. Give her the space & time, and freedom…. And the benefit of doubt.

Jews & Christians are ‘people of the book’, are they not? How do we know if she is a believing/practicing Christian?

As for chastity… “she must  be chaste” …  Why just the Sister? The ‘Muslim’ man in question is not very ‘chaste’ from what we have gathered… you would have him not marry her for ‘chastity’? The Qur’an also says that if two people have committed zina (premarital sex) they should get married.  Same ayah you are referring to I think. Scholars also advise that if two people have made a mistake/zina – they should get married. If two people have compromised their chastity with one another – they should marry each other.

Asalaamu aleikum-

Well, when I speak about reversion to Islam, I'm speaking from experience as I am a revert myself, alhamdulillah.
And why I pointed out that the woman must be chaste- and didn't mention the man- was because I was referring to what it says in Qu'ran about this- ie. that if a muslim man wants to marry a woman from the ah'l al kitab then she must be "chaste".
I don't really have any more to say on this topic- it really fills me with sadness and distaste. Ironically, when I first reverted to Islam and was very naive and new to everything, THIS sort of thing was exactly what I wanted to get away from- ie. all the fitna and haram that people tend to think is "normal" in an un-Islamic society. I thought other muslims wanted that as well, but then I learned that not everyone was is idealistic and excited to practice their religion as I am. It's a grave pity that men like this are giving others such a bad image of Islam. But Allah SWT guides whom He wills...

Hidden Pearl, I agree with you on this.  I don't understand why the poster would come here to seek advise then show him the advise she has been given, and allow him to post such an irresponsible reponse.  This is non-sense. Lady gave her very logical advise to which she didn't respond, but instead allowed him to make his outlandish comment.
